Hello,
Here's my opinion; in light of your situation, there's a likelihood that the children could become a pawn in a power struggle between you and your wife. However.....
If you stick to the facts and how they apply to your particular circumstances, you may gain a more just and fair outcome for everyone involved. For a certainty, making generalizations about a religion will probably not result in any legal advantage for you.
A competent family lawyer will definately be your best ally.
Good luck!
